Después de una inundación, el departamento de bomberos de una ciudad utiliza tres bombas para drenar agua de los sótanos inundados. Las tres bombas pueden drenar toda el agua de un sótano inundado en 6horas, 5 horas y 4 horas respectivamente. Si las encienden simultáneamente ¿en cuánto tiempo logran vaciar el sótano?

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

congruent! because each point is being moved the same distance.
